. The camera was about the same height as the light source.The acrylic base is secured to 4 LRF's (Little Rubber Feet - as alsetalokin called them) that have a yellowish tint from the warm light provided by the incandescent lamp.
Evidently, there is some shadowing by the various PMH element elevations of that particular LRF in the lower left corner. So we are getting an effect similar to that of moving shadows on the wall projected by the changing TV image illuminating stationary objects in the room. But in this case the objects are moving and the light source is stationary.
Personally, I see more action along the left margin in that light colored cloth there. That area does not have any shadows from the PMH - but it could have reflections. Whatever it is that causes the compression algorithms to flip the pixels like that must be a subtle thing. We may be trying to dismiss this as noise, but before we do, we may want to ask ourselves - why does the noise take on this wavy pattern? Could it be that the compression algorithms are just more sensitive to some underlying pattern that is concealed in the higher definition data and by the average persons POV. If so, then it would take a trained eye - or a specific algorithm to expose the patterns. As long as this is a possibility it cannot be discounted. Therefore it will take some type of proof either way to remove it as a possibility and place it into the realm of not possible or factual. I am open to suggestions on a method or falsifying test to help solidify this possibility one way or the other.
